Designation:C61214Standard Specification forMineral Fiber Block and Board Thermal Insulation1This standard is issued under the fixed designation C612;the number immediately following the designation indicates the year oforiginal adoption or,in the case of revision,the year of last revision.A number in parentheses indicates the year of last reapproval.Asuperscript epsilon()indicates an editorial change since the last revision or reapproval.This standard has been approved for use by agencies of the U.S.Department of Defense.1.Scope1.1 This specification covers the classification,composition,dimension,and physical properties of mineral fiber(rock,slag,or glass)semi-rigid and rigid board intended for the use asthermal insulation on surfaces operating at temperatures be-tween 0F(-18C)and 1800F(982C).For specificapplications,the actual temperature limits shall be agreed uponbetween the supplier and the purchaser.1.2 For satisfactory performance,properly installed protec-tive vapor retarder or barriers shall be used on below ambienttemperature applications to reduce movement of water throughor around the insulation towards the colder surface.Failure touse a vapor retarder or barrier can lead to insulation and systemdamage.Refer to Practice C921 to aid material selection.Although vapor retarder properties are not part of thisspecification,properties required in Specification C1136 arepertinent to applications or performance.1.3 The orientation of the fibers within the boards isprimarily parallel to the principal surface(face).This specifi-cation does not cover fabricated pipe and tank wrap insulationwhere the insulation has been cut and fabricated to provide afiber orientation that is perpendicular to the surface(face).1.4 This standard does not purport to provide the perfor-mance requirements of hourly-rated fire systems.Consult themanufacturer for the appropriate system.1.5 The values stated in inch-pound units are to be regardedas standard.The values given in parentheses are mathematicalconversions to SI units that are provided for information onlyand are not considered standard.1.6 This standard does not purport to address all of thesafety concerns,if any,associated with its use.It is theresponsibility of the user of this standard to establish appro-priate safety and health practices and determine the applica-bility of regulatory limitations prior to use.2.Referenced Documents2.1 ASTM Standards:2C165 Test Method for Measuring Compressive Properties ofThermal InsulationsC168 Terminology Relating to Thermal InsulationC177 Test Method for Steady-State Heat Flux Measure-ments and Thermal Transmission Properties by Means ofthe Guarded-Hot-Plate ApparatusC303 Test Method for Dimensions and Density of Pre-formed Block and BoardType Thermal InsulationC356 Test Method for Linear Shrinkage of Preformed High-Temperature Thermal Insulation Subjected to SoakingHeatC390 Practice for Sampling and Acceptance of ThermalInsulation LotsC411 Test Method for Hot-Surface Performance of High-Temperature Thermal InsulationC447 Practice for Estimating the Maximum Use Tempera-ture of Thermal InsulationsC518 Test Method for Steady-State Thermal TransmissionProperties by Means of the Heat Flow Meter ApparatusC665 Specification for Mineral-Fiber Blanket Thermal Insu-lation for Light Frame Construction and ManufacturedHousingC680 Practice for Estimate of the Heat Gain or Loss and theSurface Temperatures of Insulated Flat,Cylindrical,andSpherical Systems by Use of Computer ProgramsC795 Specification for Thermal Insulation for Use in Con-tact with Austenitic Stainless SteelC921 Practice for Determining the Properties of JacketingMaterials for Thermal InsulationC1045 Practice for Calculating Thermal Transmission Prop-erties Under Steady-State ConditionsC1058 Practice for Selecting Temperatures for Evaluatingand Reporting Thermal Properties of Thermal InsulationC1101/C1101M Test Methods for Classifying the Flexibilityor Rigidity of Mineral Fiber Blanket and Board Insulation1This specification is under the jurisdiction of ASTM Committee C16 onThermal Insulation and is the direct responsibility of Subcommittee C16.20 onHomogeneous Inorganic Thermal Insulations.Current edition approved Jan.1,2014.Published February 2014.Originallyapproved in 1967.Last previous edition approved in 2010 as C612 10.DOI:10.1520/C0612-14.2For referenced ASTM standards,visit the ASTM website,www.astm.org,orcontact ASTM Customer Service at serviceastm.org.For Annual Book of ASTMStandards volume information,refer to the standards Document Summary page onthe ASTM website.Copyright ASTM International,100 Barr Harbor Drive,PO Box C700,West Conshohocken,PA 19428-2959.United States1 C1104/C1104M Test Method for Determining the WaterVapor Sorption of Unfaced Mineral Fiber InsulationC1114 Test Method for Steady-State Thermal TransmissionProperties by Means of the Thin-Heater Apparatus(With-drawn 0)3C1136 Specification for Flexible,Low Permeance VaporRetarders for Thermal Insulat
